TANHVAT.

SPECIFICATION forming part of Letters Patent No.380,890, dated April 10,1889.

Application tiled February 12, 1887. Serial No. 227,418. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH HEAD, a citizen of the United States,residing at York, in the county of York and State ofPennsylvania,havevinvented certain new and useful Improvements in Agitators'; and I dohereby declare the following to bea full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to certain improvements in tanyats.

rlhe object I have in view is to improve the agitators used inconnectiontherewith,the improvements in said agitators consisting bothin their construction and in their position wit-h respect to thefloating frame ordinarily used for carrying the hides to be operatedupon.

In the further description of the invention reference will bc made tothe accompanying drawings, in which- Figure lis a view in perspectiveofthe hidesupporting frame and its parts, including the agitators; andFig. 2 a longitudinal section through the vat with parts in position.

Like letters refer to like partsin each view.

A represents the vat, which is of ordinary construction,and which isprovided on its interior with four corner-posts, A', each one of whichextends from the bottom of the vat to a point within` a short distanceof the top thereof, said parts serving as guides to the hide andagitator-supporting frame, and also as stops to limit the movement ofsuch frame downwardly. This hide supporting frame consists of an upperframe, B, the longitudinal bars of which are notched, as shown, toreceive the cross-strips caupon which the hides are hung, and two bottompieces, B', the top frame and bottom pieces being connected by suitablenprights, BY. The bottom pieces, B', are shorter than the longitudinalboards of frameB, and t-he uprights B2 are therefore placed on anincline, as shown in Fig. 2. The

nprights are also connected near their lower ends by crossboards B3,which form bearingpoints for the agitators now to be described.

By reference to the drawings,especially Fig. 1, it will be seen that twostyles of agitators have been shown. In connection with the one markedC,I use a strip, O,situated at or about its center, there being securedto said strip a vertical rod, C2, passed up through one longitudinalboard of frame B and formed into a suitable handle. As shown, this rodis thus connected with one side edge of the agitator, while the pivot orbearing points b thereof are in the opposite edge at each end, wherebythe elevation or depression of said rod willserve to operate saidagitator. The second style of agitator (marked D) consists ot' a boardwith trunnions c at the center of each end and provided near each sideedge of one end with suitable rings, d, to each of which one end of arope, D. is secured, said rope passing up to the top ofthe vat andserving as a medium for operating such agitator, when desired. On thetop of one end of frame B asuit-able pin or stud, e, may be provided forholding the rope when not in use.

It will be understood that when the vat is provided with the liquid thiswhole framework B O, together with the agitator,will float on itssurface, as the hide-supporting frame ordinarily does.

Vhat I claim is- The combination, with a tan-vat, of a floatinghide-supporting frame consisting of a top frame, B, notched toreccivethe hide-supporting cross-strips ,a bottom frame, B, connected totheupper frame by inclined uprights B, and cross-pieces B", connectingsaid uprights, and agitators C and D, pivoted at their ends in saidcross-pieces and provided with a rod or rope, whereby they may bevibratled, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH HEAD.
